BOOK AND SIMILAR BINDING.

Application filed February 11,1921. Serial No. 444 138.

1 00M whom it may. concern:

B'fl'dt known that I, WILLIAM P. Prrr, a

citizen of: the United States, residing at Kansas City, in the county ofJackson and State of Missouri, have invented a certain new and usefulImprovement in Book and Similar Bindings, of which the following is i aspecification.

My invention relates toimprovements in booltv and similar binding. Itrelates particularly to an improved hinge construction for connectingcover members of a book or temporary binder.

The object of my} invention is to provide a. hinge constructionof thekind described, which-is simple,cheap to make, strong and durable, notliable to get out of order, and which will permit the cover members tobe machine bound at a. minimum of expense.

My invention provides still further a novel method of making a hingecover member.

The novel features of my invention are hereinafter fully described andclaimed.

In: the accompanying drawing, which illustrates the preferred embodimentof my invention,

Fig. 1 is a perspective view, partly broken: away, of twocover membersof a binder provided with my improvement.

Fig. 2 is a plan view of one of thecover members, partly broken away,showing the sheet of binding material applied to one side of the bodyand its projecting edges unfolded.

Fig. 3is an enlarged cross section on the line 3'3 of Fig. 1.

Fig; 4- isan end elevation of the two cover members and hinge.

Fig; 5 is an end elevation ofthe channel member before it has beencompressed, and the body disposed therein.

Fig. 6 is an end elevation showing the channel member attached to thebody.

Fig. 7 is a perspective view of the channel hinge member before it hasbeen compressed to its operative position.

Similar reference characters designate similar parts in the diflerentviews.

In the drawing, which illustrates my improvement applied to a loose leafpost binder, 1 designates one member of the binder cover having mountedthereon the usual posts 2, and which is provided with one or more pintlebarrels 3 arranged to receive a pintle 4,. to which the swinging covermember is hinged. The swinging cover member comprises afiat body 5,prefera'bly of thick card board, and which is embraced at the sideadjacent to the memher 1 by a channel member 6,.which forms one memberof the hinge, the member 6 being spaced apart from the body 5,.the pin+tle 4 extending through the space thus provided. The channel member- 6is provlded on eaclr flange with one or more prongs 7 whichenter thebody 5, Fig. 6. The prongs 7 of the two sets are, preferably disposedrespectively in different transverse planes andin staggeredrelation toeach other. By means of this arrangement the opposite projections do notinterfere with each other and the body is not materially weakened alongany one line.

The body 5 extendsbeyond the ends of the member 6 a distancecorresponding to the lengths of the barrels A sheet of binding material8 is fastened I by gluing or otherwise to one side of the body 5,.andhas-its edges extending beyond the edges of the body and beyond-themember 6 during the process of manufacture. The sheet 8 has at one enda. rectangularfiap 9, which is folded over the: member 6 and is fastenedto theiopposite side ofthe body 5. The sheet 8 also has at the ends ofthe flap 9 two triangular flaps 10 which are folded over the adjacentedge of the body 5 and are attached to the inner side of the body 5, asshown inFig. 1. An inner lining sheet 11 may beglued to the inner sideof thebody, after the remaining extending. portion of the sheet 8" hasbeen folded-over the body and attachedto the inner side thereof, thelining. 11 being extended over and secured-to the folded over portionsof the sheetS.

The channel member (5 is made, preferably, of'thin metal so as to beinexpensive, and sothat it will not rise but a trifle above the surfaceof the body 5. This construction permits the cover to be machine boundand avoids expensive hand binding.

It will be noted by referring to Figs. 5 and 7 that the channel member6, before being applied to the body 5, is V-shaped, so as to permit itsbeing readily slipped over the end of the body 5. When properlypositioned on the body 5, the member 6 is compressed so as to embracethe opposite sides of the body and so as to cause the prongs 7 to enterthe body.

The binding sheet 8 in addition to serving as a finish also re-enforcesthe channel member 6 and helps to hold the latter firmly attached to thebody.

While I have shown the improvement applied to a loose leaf binder, it'will be obvious that it may be applied to books and to loose leafholders of different types, and the hinge construction may be applied tomany uses in which it may be desired to employ a cheap, strong andserviceable hinge.

I do not limit my invention to the structure shown and described, asmany modifications, within the scope of the appended claims, may be madewithout departing from the spirit of my invention.

' What I claim is 1. In a device of the kind described, a cover membercomprising a flat body, a channel hinge member embracing one end of thebody, a space adapted to receive a pintle being provided between thehinge member and the adjacent edge of the body, and a binding sheetembracing the hinge member and the body, substantially as set forth.

2. In a device of the kind described, a cover member comprising a flatbody, a channel hinge member embracing one end of the body, a space forreceiving a pintle being provided between the hinge member and theadjacent edge of the body, the body extending a substantial distancebeyond each end of the hinge member, and a binding sheet covering oneside of the body and being folded over the edges of the body and thehinge member and'attached to the other side of the body, substantiallyas set forth.

3. In a device of the kind described, a cover member comprising a fiatbody, a channel hinge member embracing one end of the body, and havingone or more projections entering the body, and a binding sheet foldedover the hinge member and attached to opposite sides of the body, aspace being provided between the hinge member and the adjacent edge ofthe body for receiving a pintle, substantially as set forth.

l. In a device of the kind described, a cover member comprising a flatbody, a channel hinge member embracing one end of the body, the latterextending a substantial distance beyond each end of the hinge member,and a binding sheet being folded over the hinge member and the adjacentexposed edge of the body and attached to opposite sides of the body, aspace being provided between the hinge member and the adjacent edge ofthe body for receiving a pintle, substantially as set forth.

5. In a device of the kind described, two cover members, one comprisinga flat body, a channel hinge member embracing one end of the body, aspace being provided between the hinge member and the adjacent edge ofthe body, and a binding sheet folded over the hinge member and attachedto opposite sides of the body, the other cover member having one or morebarrels, and a pintle mounted in said space and in said barrels,substantially as set forth.

6. In a device of the kind described, two cover members, one comprisinga flat body, a channel hinge member embracing one end of the body andhaving one or more projections extending into the body, a space beingprovided between the hinge member and the adjacent edge of the body, anda binding sheet folded over the hinge member and attached to oppositesides of the body, the

other cover member having one or more barrels, and a pintle mounted insaid space and in said barrels, substantially as set forth.

7. A hinge comprising two members, one having a barrel, the other membercomprising a body and a channel member embracing opposite sides of thebody, a space being provided between the channel member and the adjacentedge of the body, a binding sheet embracing the channel member andembracing and attached to opposite sides of the body, and a pintlemounted in said space and in said barrel, substantially as set forth.

8. A hing'e member comprising a body, a channel member embracingopposite sides of the body, a space being provided between the channelmember and the adjacent edge of the body adapted to receive a pintle,and a binding sheet embracing said channel member and embracing andattached to opposite sides of the body, substantially as set forth.

9. A hinge member comprising a body, a channel member embracing oppositesides of the body and having one or more projections entering the body,a space adapted to receive a pintle being provided between the channelmember and the adjacent edge of the body, and a binding sheet embracingsaid channel member and embracing and attached to opposite sides of thebody, substantially as set forth.

In testimony whereof I have signed my name to this specification.

WILLIAM P. PITT.
